T0 all whom t may concern:

Be it known that l, EDWARD C. AI-ILHEIM, a citizen of the United States of America, residing at Manslield, in the county of Richland and State of Ohio, have invented certain new and useful Improvements in Flush- Valves, of which the following is a specification.

This invention relates `to iush valves.V

The present invention is designed as an improvement in Letters Patent No. 1,187,595 granted to me on the 20th day of J une, 1916, and has the same objects in' view generically.

The primary object of the present invention is to provide meansof permitting and regulating the flow of water through a valve to a bowl or the like, and to arrange and locate the regulating means in such a manner as-to permit it to be adjusted to allow a predetermined flow of water therethrough from the exterior of the valve.

A further object is to provide simple7 etlicient and convenientmeans for flushing a bowl or the like, which results in saving of labor and expense in accomplishing the objects set out -in the above described Letters Patent because of the elimination of a large number of parts which are necessarily used in the construction of the device described in the above mentioned Letters Patent.

These and other objects are attained by Vthe mechanism illustrated in the accompanying drawing in which:

Figure 1 is a vertical central section of the invention showing it in its preferred embodiment. l

Fig. 2 is a horizontal section on the line O O of Fig. 1. Y

Fig. 3 is a top plan view of the invention.

The valve comprises a casing consisting of an upper section A and a lower section B fastened together in any well known manner. The upper section A of the casing is provided with vertical ribs c and CZ which are preferably made integral with a circular member e which forms part of a valve chamber. The circular member is spaced apart from the casing. A cup shaped member g is threadably connected to the circular member e thereby increasing the length and area of the chamber Y Reference numeral 1 represents an inlet and 2 an outlet which permits the flow of water to a bowl or the like (not shown). In the operation of the valve water is conducted to the inlet 1 of the valve, but is prevented from flowing through the valve mechanism to the bowl when the valve is in the closedv position shown in Fig. 1 in full lines. When the valve is open water flows through the passageway or port 3 lilling up the chamber f and its extension l1, thereby exerting a pressure upon the main valve 5 forcing it to seat as shown in full line Fig. 1.

Pressure is also exerted upon a relief valve 6 by the water thereby assisting the spring 7 to normally seat and close said relief valve. The above describes the operation and principles upon which the water exerts a pressure upon the valve mechanism closing same under normal conditions. In the operation of the valve mechanism to permit a predetermined quantity of water to pass through the valve to fiush a bowl or the like, sufficient pressure is exerted upon the push button 8 to counteract the tension of the spring 7 which in turn forces the relief' valve 6 from its seat and the pressure of the water in the chamber f and extension A is then relieved as the water is permitted to pass out of the chamber around the reduced portion of the stem 9 through the ports 10 and 11 to the casing, thence out through the outlet 2 to a bowl or the like.-

A tubular main valve stem 12 is movably mounted in a boss 13 which is provided with an aperture to movably receive the stem 9. `When the pressure of water in the chamber is relieved by the relief valve as described, further pressure is exerted upon the push button 8 forcing the stem 9 to travel until the gland nut 12', which is attached to the tubular stem is forced in contact with a lock nut 14 which is adjustably secured to the boss 13 of the valve casing.

This operation or manipulation is continued until the main valve is forced beyond the inlet l to its open position which is indicated by dotted lines in Fig. 1 permitting the water fromthe inlet to pass over the valve and out through the opening 16 provided in the circular member e into the casing; thence through outlet 2 to a bowl or the like. The quantity of water allowed to flow through the valve to a bowl or the like is predetermined by the adjustment in either direction of the lock nuts 14 and 15, the nut 14 stopping the movement of the main valve stem, thereby permitting the main valve to close the passageway or port 8 more or less to permit a predetermined quantity of water to flow through the valve. The

'of water through the valve after manipulation of the push button to impart movement thereto,the loclr nuts are adjusted to stop the movement of the main valve so as to permita larger area of the port 8 to remain vin open .communicationv with the. chamber which has the effect of accelerating the clos- 'ing of the valves on account of the increased` pressure of the water.

Attention isA called to the fact that convenience and ease of operation and adjustment of the mechanism to permit the flow of a predetermined amount of water through the valve is accomplished because all of the adjusting mechanism is -arranged upon theeXterior of the valve body which permits lthe adjustment thereof to stop the opening movement of the main valve at any point desired without dissembling any part of the said mechanism.

The 'push button 8 is counterbored to receive. and nest the spring 7, said spring being d constructed to project slightly from the face of the button to permit it to be constantly in 'contact with the gland nut 12 under compression. The stem 9 is made of such a length 4as to permit the button 8 which is attached thereto, to be maintained spaced apart from the gland nut as shown in Fig.

`l, which permits the relief valve toV be completely opened prior to the time that the gland nut 12 is forced in contact with the Y lock nut 14. The circular member e is cut .away at 17-17 to permit an increased flow f of water around the main valve at the inlet l. Y

I claim:

l. In a flush valve, the combination of a casing, a valve chamber supported within the casing and openat its lower end, a member removably connected to the lower end of the valve chamber for forming a closure therefor, said casing having an inlet port therein for delivering aliquid to the valve chamber, and having also 'a passage forming a communication between the port and valve chamber for continuously delivering liquid to the valve chamber, a valve in the valve chamber for closing the port, said valve being moved to closed position by the liquid entering the chamber through said passage, a hollow valve stem connected to the valve and in communication with the valve chamber, and provided with outlet ports, a stem slidably mounted in the hol* low stem and constructed to permit liquid to pass from the valve chamber to the ports of the hollow stem, a relief valve on said stem and adapted to be seated on said .main valve for closing the hollow stem, and a spring interposed between the ends of the stems for normally seating the relief valve, whereby the liquid entering the valve chamber through the passage may seat the main valve and close the main port.

2. In a flush valve, the combination of a casing, a valve chamber supported within the casing and open at its lower end, a member removably connected to the lower end of the valve chamber for forn'ling a closure therefor, said casing having an inlet port therein for deliveringr a liquid to the valve chamber, and having also a passage forming a communication between the port and valve chamber for continuously delivering liquid to the valve chamber` a valve in the valve chamber for closing the port, said valve being moved to closed position by the liquid entering the chamber through said passage, a hollow valve stem connected to the valve and in communication with the valve chamber, and provided with outlet ports, a stem slidably mounted in the hol low stem and constructed to permit liquid to pass from the valve chamber to the ports of the hollow stem, a relief valve 4on said stem and adapted to be seated on said main valve for closing the hollow stem, a spring` interposed between the ends of the stems for normally seating the relief valve, whereby the liquid entering the valve chamber through the passage may seat the main valve and close the main port, a gland nut on the hollow stem, and adjustable lock nuts on the casing adapted to be engaged by the gland nut for regulating the movement of the hollow stem and the opening of the inlet port.

In testimony whereof I aliix my signature,

EDWARD C. AIILHEIM.
